Freud Router Bit 12-108T 3/8 In Dia 1/2 In Shank Double Flute Straight (24000 RPM TiCo Carbide Perma-SHIELD Dado Mortising CNC Woodworking Tool)

Precision Freud 3/8 Inch Double Flute Straight Router Bit 12-108T with 1/2 Inch Shank

The Freud 12-108T 3/8-Inch Diameter Double Flute Straight Router Bit operates as a commercial-grade grooving and mortising tool engineered to execute rapid stock removal, dadoes, rabbets, and plunge cuts in solid hardwoods, softwoods, plywood, and wood composites. Manufactured with micrograin TiCo High-Density Carbide cutters treated with friction-reducing Red Perma-SHIELD non-stick coating, this 1/2-inch shank bit features end-relieved tips for direct plunge cutting, a 1-inch carbide height, and a 24,000 RPM maximum speed rating. Compatible with CNC automated routers, table-mounted setups, and handheld routers, this double-flute straight bit delivers smooth, splinter-free channel walls across cabinetry and joinery applications.

Best Used For:

• Cabinet Dado & Rabbet Cutting: Milling precise 3/8-inch flat-bottom dado channels and edge rabbets for cabinet shelving and drawer joinery.
• Deep Mortise & Blind Slot Routing: Executing clean plunge cuts and stopped mortises in solid hardwood door stiles and furniture frames.
• CNC Sheet Goods Fluting & Trimming: Routing straight grooves and perimeter cutouts in cabinet-grade plywood, MDF, and composite panels using automated CNC equipment.

Key Performance & Safety Features

• TiCo High-Density Micrograin Carbide: Titanium-cobalt carbide formulation maintains razor-sharp edges significantly longer than standard carbide when milling abrasive composites.
• Red Perma-SHIELD Thermal Barrier Coating: Non-stick fluoropolymer coating insulates the bit body against heat buildup, resin accumulation, and rust corrosion.
• End-Relieved Plunge Cutting Tips: Precision-ground bottom cutters enable smooth, vertical plunge capability for blind mortises and stopped slots.
• Heavy-Duty 1/2-Inch Steel Shank: Provides maximum anti-flex structural stability and vibration resistance during deep mortising passes.
• Double-Flute Shear Angle Geometry: Two precision-ground straight flutes shear wood fibers cleanly to deliver smooth channel floors and splinter-free side walls.
• Multi-Axis Router Compatibility: Dynamically balanced for safe operation on automated CNC spindles, router tables, and handheld routers.

Pro-Tip: When routing deep 1-inch mortises in dense hardwoods like red oak or maple using this 3/8-inch straight bit, make stepped passes of no more than 3/8-inch depth per cut. Stepping down incrementally allows wood chips to clear the flutes effectively, preventing frictional heat buildup and keeping the end-relieved TiCo carbide cutters sharp for clean, burn-free mortise walls.
